AOE 3 DE BUG. NEED TO FIX THIS ? OR NOT?

In AOE 3 DE when you playing online multiplayer (for an example 3v3 TREATY) if the starting age is Normad, before you build the TC you can go and capture any TP or build any building anywhere in the map. I feel this is a disadvantage for the opposition team, coz most of the time the people who know just go and capture all the TP’s and gets a advantage/ upper hand. And even 2 of the team mates (assuming its 3v3 match) build the TCs ,unless the 3rd player haven’t, anyone can build any building anywhere they want.
What you guys think about this ?
